SPECIFICATION forming part of Letters Patent No. 244,648, dated July 19,1881.

' Application lled Septemeer 28, 1880. (Model.) l

To all/whom it may concern:

Beit known that I, JAMES L. NEVILLE, a citizen of t-he United States,residing at OFallon, in the county of St. Charles and State of Missouri,have invented an Improvement in Stump-Extractors, of which the following-is a specification.

The object of my invention is to simplify the construction and toincrease the` efficiency and power of those stump-extractors in which acapstan, sweep, and carrier are employed.y

My improvement consists, first, in a stumpextractor provided with acapstan moved vertically and adapted to be raised by the elevating ropesor chains which are built upon themselves between the head andbearingplate in winding them around the capstan, and adapted to belowered by unwinding the said ropes or chains, as hereinafter described.

My improvement consists, secondly, in a bearing-plate having inclines orcams adapted to direct the ropes or chains over each other as they passup throughV the beam to the lcapstan, as hereinafter described.

My improvement consists, thirdly, in a stump-extractor provided with-aneveneror carrier having sheaves or pulleys at each end, in combinationwith sheaves or pulleys working within the beam, and suitable .ropes orchains passing around the sheaves or pulleys and connected with thecapstan,- as hereinafter described.

In order that my invention may he fully understood, I will proceed todescribe it with reference to the accompanying drawings, in which-v AFigure 1 is a perspective view of my improved stump-extractor, thecapstan and carrier being in their lower position. Fig. 2 is-aperspective view of the capstan and its adjacent parts, showing theropes or chains built upon themselves and the capstan and carrierelevated thereby. Fig. 3 is a vertical longitudinal section thereof.Fig. 4 is a top view of the same.

F may represent a suitable frame forming a substantial support to abeam, B, and may be mounted on vwheels W. The beam is provided with abearing plate, D, having inclines or cams I, and through which thecapvertical slot, within which are mounted lower sheaves or pulleys, PP', or upper sheaves or pulleys, P3193, in such position as to permitYthe lower end of the capstan to pass down between them centrally of thebeam.

R It are two ropesv or chains, each secured at one end to a link, L, onthe evener, then passed over a sheave, P', above, within the beam, thenunder a sheave, P2, beneath, in the evener, then passed overa sheave,P3, above, in the beam, and the other end secured beneath the head K ofthe capstan. Each sheave P3 is set obliquely to the beam, so as to bringthe outer side in line with the outer side of the lowest sheave, P2, andits inner Side in line with the periphery of the capstan, so as todirect, when the sweep' and capstan are turned, the rope or. chain infront of the vertical wall of an incline, I, beneath the under coil andonto an incline. The ropes or chains are thus built up between the headK of the capstan and the inclines, which elevates the carrier E andcapstan at the Same time. The evener or carrier is adapted to equalizethe weight brought to bear onthe capstan.

By .my construction it will be seen that great power and efficiency inworking are obtained, while the whole machine is of most simpleconstruction.

Having thus described my invention, the following s'what I claim asV newtherein and desire to secure by Letters Patent- 1. The combination ofthe sliding capstan, rope, and sweep, the capstan adapted to be elevatedby building up the coils of rope, as explained.

2. The combination of the slidinglcapstan C, having head K, ropes R It,inclines II, and a suitable sweep, as set forth. p
